SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 448,339, dated March17, 1891.

Application filed May 2, 1890. Serial No. 360,364. (No model.)

To aZZ whom it nmy concern:

Be it known that 1, WILLIAM M. HAZEL, a citizen of theUnitedStates,residin g at Georgetown, in the county of Sussex and State ofDelaware, have invented a new and useful Sash-Holder, of which thefollowing is a specification.

The object of my invention is to provide a simple and effectivesash-holder-one that will adjust itself and be held in place without thenecessity of grooved notched slots, adjustable tables, springs, or othermovable devices in order to get proper bearing.

The invention consists in the peculiar for- 5 mation of the box, andalso in the novel construction of the wheel or ball which plays freelyin the same, all of which will be more fully set forth in thespecification, and shown in the drawings, wherein- Figure 1 represents asection of box and its inner walls on line 1 1 of Fig. 3, with the wheelor ball in position. Fig. 2 represents a similar section 011 line 2 2,with the wheel or ball in a bearing position in said box. Fig. 3repsents a front view of the sash-holder complete.

Fig. 4. represents a side view of box and wheel or ball in bearingposition. Figs. 5 and 6 show modified forms of wheel or ball shown inFigs. 1 and 2.

Similar letters of reference indicate like parts in the severaldrawings.

My invention is made of metal, and the box B is constructed withvertical outside walls and grooved inside walls, with its rear wallflattened fora portion of its width and somewhat inclined, as shown inFig. 4 of the drawings. This box is preferably cast in two pieces andfitted together at the point shown by the lines I) in Fig. 3, or it maybe cast in one piece,

4 as desired,the result being the same in either case. \Vheu so cast intwo pieces, the front edge of one member is provided at its upper endwith an inwardly-extending tongue 6, havin g a hole 72, through which ispassed the screw that holds the box in the sash, and the other memberhas a similar tongue at its lower end. The wheel or ball A may be madeof metal or molded from a composition of hard material, it being onlynecessary that it shall have 5 no elastic properties. In shape it isspherical at the parts lettered a, which fit in the grooved I placed.

inner sides or walls of the box B, as shown in dotted lines in Fig.3 andin full lines in Flgs. 1 and 2, and it is provided at the pointslettered a a with a raised, rounded, flattened, or angular'faced ring,which rests against the rear wall of the box 13 and against the edge ofthe window-frame if the box be seated in the sash, or against the sashif conversely This ring is comparatively narrow- 6., narrower than theedge of the sash or the groove in the frame in which the sash moves aswill be seen from the drawings, and hence when a considerable strain isbrought to bear upon the ball it will sink into or 111- dent the sash orframe.

In operation, the parts being properly placed in a window, the wheel orball A rolls freely up and down in the box B when moving the window upor down, and when pressure is taken off the sash the wheel or ball Adrops readily into a bearing position against edge of sash. The wheel orball A being made slightly raised at the points a Ct, it w1ll beobserved, is a great improvement, because 1n use, being narrower thanthe edge of the sash, it will gradually embed itself in said sash orframe, and thus increase its holding qualities, as Well as positivelyprevent the rattling of the window.

I show'iu Figs. 5 and (3 modified formsof my invention. which may beemployed with the box without departing from the spirit ofthis'invention, as the results are identical.

It will be observed that my invention by reason of the grooved innerside walls of box and novel construction of wheel or ball gives such astubborn resistance all around the grooved walls and the ball as tocompel the sash to remain in position desire-d when the wheel or ball isat rest against the indented edge of sash, thus forming a very strongattachment and one that cannot get out of order or become detached. Atthe same time it adjusts itself from time to time as the window mayshrink or swell. These features are decided improvements, which will bereadily appreciated by builders, because when once set the job iscomplete, as no future ad ustment becomes necessary.

Heretofore much difficulty has been experienced in devices of thischaracter, owing to the crushing or breaking of the boX if the sash wereforced strongly downward when held by the ball. This was owing to thefact that where spherical balls were used theybore at but one pointagainst the box and where the balls were cylindrical they bore onlyacross a single line. The box being generally of light casting waseasily crushed if too great pressure were brought to bear thereon; butwhere the spherical faces a a travel in grooves in the side walls andthe raised faces a bear squarely against the rear wall of the box adouble, or rather triple, bearing or resistance is provided in the box,the spherical faces wedging the sides of the box outwardly and the flatface driving its rear wall backward. The strain resulting is thereforedistributed over a considerable part of the box and exerted in threedirections, and the result is that the box is much less likely to bebroken or crushed.

against said rear wall and extending beyond the front of the box when inits operative position, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
